One of the most important tools the federal government has for cracking down on greenhouse gas emissions is a single number: the social cost of carbon. It represents all the damage from carbon emissions — everything from the cost of lost crops and flooded homes to the lost wages when people can't safely work outside and the cost of climate-related deaths. Currently, the cost is $51 per ton of carbon, but the Environmental Protection Agency has proposed raising the cost to $190. NPR climate correspondent Rebecca Hersher tells Aaron how the change could dramatically alter how the government confronts climate change, and why the new number is simultaneously more accurate and an ethics nightmare.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

In the wake of the massive earthquake in Turkey and Syria, many scientists have been saying this area was "overdue" for a major quake. But no one knew just when: No scientist has "ever predicted a major earthquake," the U.S. Geological Survey says. Even the most promising earthquake models can only offer seconds of warning. In this episode, host Emily Kwong talks to geologist Wendy Bohon and NPR science correspondent Geoff Brumfiel about why earthquake prediction can be so difficult, and the science that fuels these models.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

The James Webb Space Telescope is by far the most powerful space-based telescope ever deployed by the United States. But it is only one instrument, and scientists all over the world have to share. The JWST's managers received more than 1,600 research proposals for what the telescope should look at. When an astronomer or a team does get some much-coveted telescope time, they currently get exclusive access to whatever data they collect for a full year. But there is a movement in astronomy to make most results open-access right away. That might speed up the pace of scientific discoveries and open up the data to a much wider set of researchers. On the other hand, some astronomers worry that instant open access would mostly benefit researchers who already have advantages. In this episode, NPR's Nell Greenfieldboyce talks with Short Wave scientist in residence Regina G. Barber, who has firsthand experience competing for telescope time, about who gets dibs on the data, and how that could affect equity in astronomy.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
